A client liked our Gantt chart solution for SharePoint Task and Project lists they asked if we could do the same thing for SharePoint Calendar lists. With the IntelliGantt Web Part we could actually configure it just so by tweaking this setting and adjusting that knob that we could basically show a calendar. Now we've gone the rest of the way and created a new package expressly for calendars and events.
Here is what it looks like:
The IntelliEvent Web Part will find all the Calendar lists in a SharePoint site and display them on the adjustable timeline. You can include calendars from other sites as well to create rollup calendar views. Of course everything is still editable by either clicking in a cell or dragging on the chart.
We've also changed a few other things to make the IntelliEvent Web Part calendar friendlier like solid colors for the timeline, calendar specific information in the popups and a default 'calendar centric' view.
